> About this stupid patent thing. The l-amphetamine in Adderall is a significant part to the med. It has no negative side effects. You wouldn't know unless you tried them all and got other people's input. Adderall is similar to Dexedrine, but is very different at the same time. The're not "altering one atom". You're theory is completely wrong.
James here....
Least patentable difference is not my theory but a common term in the pharmaceutical industry. It drives many patents. I used the anology of "altering one atom" cuz you did not seem to get it the first time. It is difficult to describe 3-D chemistry in words. In the case of d or l amphetamine it is not one atom but position that is altered. In some cases it is the addition or subtraction of a one or a few atoms. This is enough of a difference to get a patent.
